Revamp Local Fortune Server Example: Declare sendFortune() as a method

Declare sendFortune() as a method because it's used in the connect()
overload taking a pointer-to-member-function, so it doesn't need help
from moc.

Q_OBJECT is not needed anymore as the "Server" class doesn't contain
signals and slots anymore.
Use Q_DECLARE_TR_FUNCTIONS Macro to allow tr() calls.
